Boston Scientific Earns FDA Approval for ImageReady MR-Conditional Pacing System

Approval includes Accolade MRI and Essentio MRI pacemakers and Ingevity MRI pacing leads

Boston Scientific, FDA, ImageReady MR-Conditional Pacing System

April 28, 2016 — Boston Scientific has received U.S. Food and Drug Administration (FDA) approval for a suite of products deemed safe for use in a magnetic resonance imaging (MRI) environment.

The ImageReady MR-Conditional Pacing System, which includes Accolade MRI and Essentio MRI pacemakers, as well as the new Ingevity MRI pacing leads, is designed to treat bradycardia, a condition in which the heart beats too slowly. Patients implanted with the full system are able to receive full-body MR scans in 1.5 Tesla environments when conditions of use are met.

The newly-approved family of Ingevity MRI pacing leads includes active and passive fixation models. This marks the first time a passive fixation pacing lead is approved for U.S. patients undergoing MR scans.  

Approval of the Ingevity MRI leads, as well as the full ImageReady System, was based on data from two global clinical trials. The INGEVITY trial, a prospective, non-randomized study, enrolled 1,036 patients and assessed safety, performance and effectiveness of the leads in patients with a single or dual chamber pacemaker. The SAMURAI trial, a prospective, randomized study, enrolled 351 patients and evaluated safety and effectiveness of the ImageReady System for use in patients with a single- or dual-chamber pacemaker when used in an MRI environment.

"As shown in the SAMURAI trial, the ImageReady System gives physicians reassurance that they are implanting pacemakers that are safe in an MRI environment should their patients need scans in the future," said Ronald D. Berger, M.D., Ph.D., principal investigator of the SAMURAI trial and professor of medicine and biomedical engineering at Johns Hopkins Medical Institutions. "The study demonstrated the Ingevity MRI leads had no MR-related complications and very low rates of complications overall."

The ImageReady System offers automatic daily monitoring via the Latitude NXT Patient Management System. An increasingly important tool for physicians, automatic daily monitoring has been shown to improve survival in patients with pacemakers. The Latitude NXT wireless system allows for earlier intervention and improved patient outcomes by providing physicians with device and patient information through customizable alerts.

The company is also actively pursuing MRI compatibility for their currently approved implanted cardiac defibrillation (ICD) and cardiac resynchronization therapy (CRT) systems via the global ENABLE MRI study, which was initiated earlier this year. Trial findings will be submitted to regulatory agencies in Asia and the United States, when the company requests updated labeling for MR-conditional use on ICD and CRT systems, including those that have been previously implanted.
